How to Deep Clean the High Lifter Water Pump Disc Filter

For the Dig Filter, used from 2010 to the present: 1) Remove Filter Element from Filter Housing
2) Remove the spring and pry off the holding ring with a small screwdriver.
3) Remove discs and clean each one with a toothbrush. This is tedious but it is the only way to get rid of encrusted algae buildup which can seriously clog the element even though it looks clean.
Procedure for the Arkal Filter, used before 2010, is pretty much the same. Just insert a screwdriver and twist off the holding ring.
